How to implement Device ID+ with BIG-IP ASM/AWAF

i'm able to log diA & diB using irule provided by Anulfo Hernandez

when HTTP_REQUEST {
    if [HTTP::cookie exists _imp_apg_r_] {
        set deviceid [URI::decode [HTTP::cookie _imp_apg_r_]]
        log local0. "URL Decoded cookie is $deviceid"
        set deviceida [lindex [regexp -inline -- (?:"diA":")(.*?)(?:") $deviceid] 1]
        log local0. "diA = $deviceida"
        set deviceidb [lindex [regexp -inline -- (?:"diB":")(.*?)(?:") $deviceid] 1]
        log local0. "diB = $deviceidb"
        log local0. "IP is [IP::client_addr]"
        log local0. "Path os [HTTP::path]"
    } else {
    log local0. "No cookie"
    }
}

now i want to use it with bot defense how to match on diA?

 when BOTDEFENSE_ACTION {
     if {[$diA equals {"[AYrQyWEAAAAACxF5RBPJyPdDICteKxbw"}]} {
         set res [BOTDEFENSE::action block]
		 log local0. "Mohanad is Blocked"
     }
 }
